Participants were 18 to 65\u2009years old with episodic migraine. Enrollment was halted early due to recruitment delays. Participants were exposed to two joint experimental manipulations involving stress and fasting: (1) a randomized 12\u2010h fasting or nonfasting condition, and (2) a fixed sequence administration of the Trier Social Stress Test (stress) or a time\u2010matched control task (control), each administered on separate study visits. The primary outcome was an incident headache attack rated \u22654\/10 or treated with abortive or analgesic medication within the 6\u2010h laboratory session.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Among 131 analyzable sessions from\n                      <jats:italic>N<\/jats:italic>\n                      \u2009=\u200974 participants, eight (6%) incident headache attacks were observed.

Compared to Control\/No\u2010Fast, adjusted posterior odds ratios were 1.54 (95% CrI: 0.39 to 6.5) for Control\/Fast and 1.86 (95% CrI:0.48 to 8.1) for Stress\/Fast.
